Nursing Elites

1. Anemia of chronic inflammation is generally classified as:

• A. hypochromic and microcytic.
• B. hypochromic and macrocytic.
• C. normochromic and microcytic.
• D. normochromic and normocytic.

Correct answer: D

Rationale: Anemia of chronic inflammation is characterized by normochromic and normocytic red blood cells. In chronic inflammation, the body typically produces enough red blood cells, but they are often smaller and paler than normal (normocytic and normochromic). Choices A, B, and C are incorrect because hypochromic and microcytic, hypochromic and macrocytic, and normochromic and microcytic anemias are not typically associated with chronic inflammation.

2. What key contraindication should the nurse emphasize to a patient prescribed sildenafil (Viagra) for erectile dysfunction?

• A. Sildenafil is contraindicated in patients taking nitrates due to the risk of severe hypotension.
• B. Sildenafil should not be taken with food as it can reduce its effectiveness.
• C. Sildenafil is contraindicated in patients with a history of hypertension.
• D. Sildenafil should not be taken with grapefruit juice as it can lead to dangerous side effects.

Correct answer: A

Rationale: The correct answer is A. Sildenafil is contraindicated in patients taking nitrates due to the risk of severe hypotension. Nitrates and sildenafil both cause vasodilation, leading to a synergistic effect that can result in a dangerous drop in blood pressure. Choices B, C, and D are incorrect because there is no specific contraindication for taking sildenafil with food, having a history of hypertension, or taking it with grapefruit juice. The main concern is the concurrent use of nitrates with sildenafil.

3. Which of the following characteristics is common in both malignant and benign tumors?

• A. Uncontrolled cell growth
• B. Rapid growth
• C. Metastasis
• D. Invasion of surrounding tissue

Correct answer: A

Rationale: The correct answer is A: Uncontrolled cell growth. This characteristic is common to both malignant and benign tumors. Benign tumors are non-cancerous growths that do not invade nearby tissue or spread to other parts of the body. Therefore, choices B, C, and D are incorrect. Rapid growth, metastasis, and invasion of surrounding tissue are characteristics typically associated with malignant tumors.

4. A patient taking an oral contraceptive missed one pill. What should the nurse teach the patient to do?

• A. Take two pills as soon as you remember, then continue the regular schedule.
• B. Take one pill as soon as you remember, then continue the regular schedule.
• C. Skip the missed pill and continue the regular schedule.
• D. Take two pills immediately, then continue the regular schedule.

Correct answer: A

Rationale: When a patient taking an oral contraceptive misses one pill, the correct action is to take two pills as soon as they remember and then continue the regular schedule. Option A is the correct answer because doubling up the dose helps maintain the effectiveness of the contraceptive. Option B is incorrect because taking only one pill after missing one may decrease contraceptive effectiveness. Option C is wrong as skipping the missed pill can also reduce effectiveness. Option D is inaccurate because taking two pills immediately is not necessary; the patient should take the missed pill as soon as remembered and then resume the regular dosing schedule.

5. In a patient with chronic kidney disease and a hemoglobin level of 9 g/dL, which of the following treatments is most appropriate?

• A. Iron supplementation
• B. Erythropoiesis-stimulating agents
• C. Blood transfusion
• D. Vitamin B12 supplementation

Correct answer: B

Rationale: In chronic kidney disease, anemia commonly occurs due to decreased erythropoietin production. Erythropoiesis-stimulating agents, such as erythropoietin or darbepoetin, are the mainstay of treatment to stimulate red blood cell production. Iron supplementation is more appropriate for iron-deficiency anemia, not the anemia of chronic kidney disease. Blood transfusion is reserved for severe cases or acute blood loss. Vitamin B12 supplementation is indicated for megaloblastic anemia caused by vitamin B12 deficiency, not specifically in chronic kidney disease-related anemia.
